An intercostal nerve block is a block of nerves that lie beneath the lower edge of every rib. For certain types of injuries, e.g., rib fractures, nerve injuries to the chest wall, postoperative pain alongside the rib nerves (“intercostal nerves”), injection of a small amount of local anesthetic can substantially diminish pain.
Intercostal nerve block provides great analgesia in patients with rib fractures and for postsurgical pain after chest and upper abdominal surgical procedure consisting of thoracotomy, thoracostomy, mastectomy, gastrostomy, and cholecystectomy. Respiratory parameters generally show impressive enhancement on relief of pain. Blockade of the 2 dermatomes above and the two underneath the level of surgical incision is required. Neurolytic intercostal nerve block is used to control persistent pain conditions along with postmastectomy pain (T2) and postthoracotomy pain.
What medications are injected?
The diagnostic injection consists of local anesthetic, or in some situations with a combination of steroid along Celestone.
How is an intercostal nerve block proceed?
First, you’ll accept an intravenous medicine to relax you. Then, you’ll lie for your side — the one no longer inflicting pain.
The physician will use antiseptic to clean a place of skin near your ribs to start the procedure of intercostal nerve block . Then she or he will:
- Insert a skinnyneedle underneath your rib and inject anesthetic
- Use x-ray steerageto insert a 2nd needle and inject a steroid pain medication
- Usually, the processtakes less than 30 minutes, and you could go home the same day
What to expect from intercostal nerve block injection?
Shortly after the intercostal nerve block injection, you might notice that your pain may be gone or extensively less. You may be kept in the recovery room for a short duration for observation. Very rarely, this injection can result in a complication known as a pneumothorax (collapsed lung) so a chest x-ray can be obtained.
The long-term effect of the medication cannot be predicted. For the diagnostic injection, the period is simplest for the effectiveness of the local anesthetic.
If the first injection is successful but the pain returns, you’ll be eligible for some other injection, in case you had relief from pain for an inexpensive duration of time.
Patients who shouldn’t have the injection
The following patients should no longer have intercostal nerve block injection: in case you are allergic to any of the medicines to be injected, if you are on a blood-thinning medication (e.g. Coumadin, injectable Heparin), or if you have an active contamination going on. With blood thinners like Coumadin, your doctor may recommend you to stop this for 4-7 days ahead or take “bridge therapy” with Lovenox prior to the procedures. Anti-platelet drugs like Plavix may should be stopped for 5-10 days prior to the procedure.
